Patent CA-2212502-A1 (CA)
Title: New emitter unit forms
Inventor: DERMITZAKIS EMMANUIL
IPC: A01G25/02
Filed: 1996-02-07
Abstract: The invention refers to conventional emitters with a path for the water pressure drop which consists of repeated parts of a basic prismatic form (1) which is contained within convex (1b) and concave (1a), almost cylindrical in shape surfaces, at right angles to the base (2), which converge to a perpendicular edge (3). In the regions of the convave surfaces, cylindrical craters (4) are raised from the bottom, half way along the emitter height, forming hydrocyclones. Prismatic wedge-shaped forms (5) are also developed radially from the base along half of the emitter height. As far as the self-compensating emitters are concerned, our invention refers to an arrangement for water filtering at the inlet of the emitter which consists of an elastic membrane (24) which covers peripherally the mouths of a closed cavity (33) with radially engraved channels (18) of a small depth. Self-compensation is achieved in successive stages and in several cavities (31, 33) of the path by a combination of a couple of holes for the inlet and outlet of the water into the cavities and of a membrane. The membrane (24) balances at same height above all of the cavities and water paths which are arranged in series.

Title: On-load tap changer of a step switch
Inventor: PILLMEIER LEONHARD
IPC: H01H25/06
Filed: 1996-01-31
Abstract: The invention relates to an on-load tap changer of a step switch with an energy accumulator having a lifting slide continuously movable by a drive shaft and a depressor actuating a switching shaft. According to the invention, on the switching shaft there is an axially movable insert bearing cam discs to actuate vacuum switches and mechanical switching components. Depending on the switching direction, i.e. the linear movement of the lifting slide of the energy accumulator, the switching insert is taken to an upper or lower position on the switching shaft in such a way that different cam discs become operative. It is possible with this on-load tap changer to make asymmetrical circuits in which there is the same sequence of switchgear to be moved or actuated regardless of the switching direction.
